As I recall this is one of the reasons that Jarkko wants to keep the DMA and McBSP related code separately (to have the possibility to add the EAC support with the least code duplication). As I recall on OMAP2 the EAC had some bugs, which prevented it's use in certain situations, thus the McBSP mode was preferred over EAC. But yes, adding the EAC dai should be possible for OMAP. -- Péter -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
